DRAFT-EXCLUDER FOR DOORS.

To all whom it may concern:

Be it known that I, GEORG GTTE, a subject of the German Emperor, andresiding at Cassel, in the German Empire, have invented certain new anduseful Improvements in Draft-Excluders for Doors, of which the followingis a specication.

My invention relates to an improved draft excluder for closing thecrevice between the threshold and the Iower edge of the bottom rail of adoor.

In prior draft excluders of this class the movable draft excluding stripis raised or lowered during opening and closing of the door. Accordingto my invention, on the other hand, the strip is lifted immediately thedoor handle is turned, so that it is impossible for it to drag on theoor. In this matter carpets, mats, rugs and the like can be laid rightup to the door, or even under it if the usual sill is dispensed with.

My invention is illustrated in the accompanying drawing, in which-Figure l is an elevation of portions of a door fitted with the new draftexcluder, fragments of the bottom rail and stile being removed todisplay underlying parts. Fig. 2 is an elevation of the door lock, drawnto a larger scale. Fig. 3 is an elevation and part longitudinal sectionof fragments of the bottom rail of the door, drawn to the same scale.Fig. l is a cross section through a fragment of the bottom rail, drawnto the same scale. Fig. 5 is an elevation of the auxiliary latchemployed, drawn to a larger scale, the cover-plate being removed.

rIhe under edge of the bottom rail a of the door is provided with agroove e, into which there is fitted a wooden strip Z) preferablyfurnished with metal rails or anges c and having mounted on it smallpulleys Z1.. In the groove c, between the anges c, there is provided adraft excluding strip f of felt, rubber or the like, which may besuitably held between two metallic rails cZ. In the stile o of the doorthere is fixed a latch p having an upright bolt la; and above thisauxiliary latch is the actual door lock g, which, in addition to theusual latch bolt j, operated by the lever handle r, has pivoted to it abent lever Z. One of the arms of this lever engages with the latch bolty', while the other is attached by a cord or the like a and screw t tothe top end of the bolt of the latch p. The other end of the boltSpecification of Letters Patent.

/c stands in engagement with the draft excluding strip f eZ through theagency of a cord or the like g, secured by screws a u and passing overthe pulleys L. Pivoted to the side plate of the latch p there is atumbler Z, which is weighted so as to bear continuously against ahorizontal bolt m, adapted to engage in the notch of the bolt Ze andlock the latter when in its elevated position. The bolt is disengaged bythe bolt m on the latter striking a pin s projecting from the door jamb.

The operation of the device is as follows I/Vhen the handle r is turnedthe latch bolt j is retracted and the bent lever z' thus actuated,whereby the cord n is caused to lift the bolt la, while the latter drawsupon the cord g. The draft excluding strip j' cZ is thus lifted,receding into the groove c so that it can not drag upon the floor. Inthis position of the parts the load of the tumbler Z acting on the boltm will shoot the latter, thus locking the bolt Za in its elevatedposition, so that this bolt can not drop on release of the handle r. Onthe door being closed again, however, the bolt m strikes the pin s andis thus pushed back against the action of the weighted tumbler Z. Thebolt c is thus released and drops, whereby the pull on the cord g isremoved. The draft excluding strip f Z thus drops and protrudes againfrom the groove e, covering the crevice between bottom rail a andthreshold.

Having thus described my invention, I declare that what I claim as newand desire to secure by Letters Patent isl. In combination, a door whosebottom edge presents a groove, a draft excluding strip located in thegroove, a latch secured to the door and having a vertically slidingbolt, a tumbler automatically locking the bolt in its raised positionand means for automatically releasing the bolt on closing of the door, adoor lock located above the said latch, and a bent lever pivoted to thelock and having its one arm engaged by the latch bolt of the lock,flexible means connecting the other arm of the lever with the verticallysliding bolt, and flexible means engaging the draft excluding strip andattached to the lower end of said bolt, whereby on the latch bolt of thedoor lock being retracted the lever is turned, the vertically slidingbolt lifted and locked and the draft excluding strip withdrawn into thegroove, while on closing of the door the said'bolt is released and thedraft excluding strip allo-Wed to drop, substantially as described.

2. In combination, a door Whose bottom edge presents a groove, a draftexcluding strip located in the groove, a latch secured to the door andhaving a vertically sliding notched bolt, a horizontally sliding memberand a pivotal Weighted tumbler adapted to cause engagement between saidmember and bolt, and means for automatically releasing said member fromthe bolt on the door being closed, a door lock located above said latch,and a bent lever pivoted to the lock and having its one arm engaged bythe latch bolt of Ythe lock, flexible means connecting the other arm ofthe lever With the vertically sliding bolt, flexible means engaging thedraft excluding strip and'attached tothe lower end of said bolt, andpulleys mounted in the groove, over Which said latter flexible meansruns, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
